Multiple target tracking and OpenCV+vs

Description

First with the background to complete the goal differential extraction, will be placed in the moving target relevant information to the list, the completion of multi-target tracking by frame difference, achieve real-time requirements

Moving target relevant information stored in the structure, it is possible to determine the target of the action based on this basic framework for behavior tracking, opencv written using background subtraction, centroid method can track multiple targets, and assigned an ID number, the track record of action available road vehicle, etc., we can refer to learning, the effect could be improved, different video have different effects.
